High-redshift quasars at z >= 3
We present a study of the radio variability of bright, S_1.4_>=100mJy, high-redshift quasars at z?=3 on timescales of up to 30-40 yrs. The study involved simultaneous... -
The GALEX-PTF experiment. II. Core-collapse SNe
The radius and surface composition of an exploding massive star, as well as the explosion energy per unit mass, can be measured using early ultraviolet (UV) observations of... -
PZWav miniJPAS detection of galaxy clusters
Galaxy clusters are an essential tool to understand and constrain the cosmological parameters of our Universe. Thanks to its multi-band design, J-PAS offers a unique group and... -
Catalog of FR-II radio galaxies
We present an independent catalog (FRIIRGcat) of 45241 Fanaroff-Riley Type II (FR-II) radio galaxies compiled from the Very Large Array Faint Images of the Radio Sky at... -
SRG/eROSITA zsp of 216 galaxy clusters
We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The... -
DESI Peculiar Velocity survey
We describe the target selection and characteristics of the DESI Peculiar Velocity Survey, the largest survey of peculiar velocities (PVs) using both the fundamental plane (FP)... -
Temporal analysis of GRB precursors in Swift-BAT cat.
We select 52 long gamma-ray bursts (GRBs) that have precursor activity in the third Swift-BAT catalog. Each episode shown in both the precursors and the main bursts is fitted by... -
Seyfert 1 AGNs with X-ray sp. from NuSTAR+Swift
The corona is an integral component of active galactic nuclei (AGNs) which produces the bulk of the X-ray emission above 1-2keV. However, many of its physical properties and the...
